Ford → Space Systems Loral (SSL): SSL-1300

The 1300, a powerful, space-proven platform for a wide range of services, has been in
constant evolutionary development to deliver increasingly greater power, communications
capability, and longer useful life, keeping the company in the forefront of satellite
technology.

Total satellite power ranges from 5 to 12 kW continuously throughout the life of the
spacecraft. On-board transmitter power – exceeding 5,000 RF watts – can
accommodate as many as 70 active transponders. Launch mass tops out at approximately 5,500
kg. Standard satellites in the 1300 line will fit into a 4 meter launch-vehicle fairing.

The size and capabilities of the 1300 can be expanded to generate and process more
power, and accommodate larger, more powerful payloads. In total, these changes can provide
up to 40 percent more capacity than available in the basic model, ideal for any of today's
demanding multi-band and spot-beam payloads. The expanded models feature total satellite
power that ranges from 12 to 18 kW throughout the life of the spacecraft, and on-board
transmitter power – approaching 10,000 RF watts – that can accommodate as many
as 90 active transponders. Launch mass of the largest version tops out at approximately
6,700 kg. This version was earlier called 1300S.

With all of their features and power, satellites in the 1300 line will fit into a
5-meter launch-vehicle fairing.

Loral does not use (anymore?) the sometimes reported designators for sub-versions like
1300E, 1300HL, 1300S, 1300X.
